JPsec – Tailored IT solutions for complex infrastructures

JPsec is a specialized IT company that excels in developing and implementing customized solutions for diverse Linux and Unix environments. Since 2007, I have been dedicated to helping organizations optimize their IT infrastructures, ensuring they are both efficient and future-ready. My client base spans a wide range of industries, including the public sector, healthcare, finance, media, manufacturing, and more.

My Philosophy: Empowering sustainable infrastructure management through knowledge and tools

I equip my clients with the skills and resources to independently and efficiently manage their IT infrastructures. By reducing reliance on third-party vendors, hardware, and software components, I help lower costs and enhance long-term flexibility.

My Experience: A passion for Open Source, Linux, and Unix-based systems

With 18 years of experience in IT, I specialize in Linux and Unix-based systems, including Illumos, SmartOS, Solaris, BSD derivatives, and macOS. I am a strong advocate for free and open-source software, combining the benefits of professional support with the innovation and collaborative nature of open-source development. This approach enables me to leverage the flexibility, extensibility, and security of open software.

Throughout my career, I’ve successfully designed, planned, and implemented complex network architectures, both on-premises and in the cloud or data centers. In the defense sector, I’ve developed solutions that meet the highest security standards, ensuring maximum performance, stability, and reliability in security-critical and highly available environments.

My Focus Areas: Network Architecture, Virtualization, and IT Process Automation

My work is centered around automating IT processes, developing robust network architectures, and managing system and software installations. I handle every aspect of software packaging, patch management, and system configuration to ensure a stable and sustainable infrastructure for my clients, providing them with long-term reliability and performance.
